Title:
STEPPING MOTOR DRIVE CIRCUIT
Document Type and Number:
Japanese Patent JPH0686597
Kind Code:
A
Abstract:
PURPOSE: To facilitate the selection of a fuse.
CONSTITUTION: A diode D is provided between a connecting point T11 for first smoothing capacitor C1 of a drive-power-supply-side electric path 11 and a fuse 5 or between the fuse 5 on a phase-coil-side electric path 12 and a connecting point T12 of a second smoothing capacitor C2. The diode D blocks the inflow of a current i2 based on the mutual induction caused by the switching of one phase coil (A) and the other phase coil (C) of a stepping motor 10. These parts are provided.
